feat: full support UiTransform in bevy 0.17

CHANGELOG.md

@@ -15,8 +15,15 @@ You can find its changes [documented below](#0102---2025-06-29).
 
 This release supports Bevy version 0.17 and has an [MSRV][] of 1.87.
 
+### Changed
+
+- Some diagnostics were changed.
+  - `VelloEntityCountDiagnosticsPlugin::SCENE_COUNT` was split into `VelloEntityCountDiagnosticsPlugin::WORLD_SCENE_COUNT` and `VelloEntityCountDiagnosticsPlugin::UI_SCENE_COUNT` to more granularly track Ui and World entities.
+- The `VelloScreenSpace` marker component has changed to `VelloRenderSpace::Screen`.
+
 ### Fixed
 
+- Components that were marked with `ScreenSpace` no longer *always* render over components without them. Now it is correct - Screen space renderables will be sorted by their respective transform's Z value.
 - Render targets are now resized when camera viewport size changes
